Powerful audio interface with QUAD Core Processing.

The Apollo Twin X QUAD Heritage Edition from Universal Audio is their flagship desktop audio interface, designed to deliver elite audio quality and processing power for recording musicians and engineers. Powered by a QUAD Core UAD chip, the Apollo Twin X QUAD Heritage Edition allows you to run UAD plug-ins with near-zero latency, including emulations of legendary studio gear. Two Unison-enabled mic preamps provide exacting models of coveted preamps like the Neve 1073, UA 610-B and API 312, allowing you to capture vocals and instruments with the character of analog gear.

Flawless Audio Conversion and Monitoring

With premium A/D and D/A conversion, the Apollo Twin X QUAD Heritage Edition provides pristine audio quality for recording and playback. Its onboard DSP allows for Accelerated Realtime Monitoring, giving you a clear picture of how your tracks will sound with effects like reverb, compression and EQ at near-zero latency. The Apollo Twin X QUAD Heritage Edition has dedicated monitor controls, as well as an onboard talkback mic, providing an all-in-one solution for controlling your studio monitors and communicating with musicians.

Unparalleled Processing Power

The Apollo Twin X QUAD Heritage Edition is powered by a QUAD Core UAD chip, Universal Audio's most powerful DSP. This allows you to run UAD plug-ins like the LA-2A and 1176 compressors, Pultec EQs and UA guitar and bass amp simulators with near-zero latency, letting you capture and monitor tracks with the tone of classic analog gear. The Apollo Twin X QUAD Heritage Edition comes with Realtime Analog Classics, a bundle of UAD plug-ins, as well as a suite of 5 additional plug-in titles to get you started.

Full Integration With LUNA Recording System

The Apollo Twin X QUAD Heritage Edition works as the centerpiece of LUNA Recording System, Universal Audio's fully integrated DAW. LUNA provides an intuitive workflow for recording, editing and mixing, with features like timeline editing, elastic audio and automatic delay compensation. Combined with UAD plug-ins and Accelerated Realtime Monitoring, LUNA lets you capture and mix professional-sounding tracks with the Apollo Twin X QUAD Heritage Edition.

Expandable System

The Apollo Twin X QUAD Heritage Edition works on its own as a desktop interface, but can also be combined with up to three additional Thunderbolt Apollos for more I/O and DSP power as your studio grows. Once expanded, the Apollo Twin X QUAD Heritage Edition can function as a monitor control surface, with its front panel controls and talkback mic managing your entire monitoring setup.
